Do I need to configure gcc with any specific options when building gcc for this to work properly? I do see the expected "L" symbols type in libstdc++: $ /usr/bin/nm /opt/act-gcc-5.3.0/lib/gcc/powerpc-ibm-aix6.1.8.0/5.3.0/../../../pthread/libstdc++.a | grep __once_callable ._ZSt15__once_callable d 537213852 4 _ZSt15__once_callable L 4294935556 _ZSt15__once_callable d 537213856 4 _ZSt15__once_callable:G139 - 4
